 however, even if muddy, provided some pure 

 water can be used occasionally, to enable the 

 attendant to see tbe ova, and by the very 

 frequent use of the watering-pot to wash off 

 the sediment. I have known trout ova 

 hatched out very successfully by Mr. Eich- 

 mond, at Learmonth, in water raised by a 

 windmill from the lake, which was so muddy

 until a few buckets of rain water were poured 

 into the hatching-boxes — which was done 

 daily to make the ova or fish visible, so that 

 dead eggs or fish might be removed. These 

 ova were within a few days of hatching, how-

I will now describe the hatching-boxes, 

 which I have used with success, and which 

 are very convenient,' and in every way suitable. 

 They are about 6 feet long by 18 inches
